Centos修改yum源

1.备份/etc/yum.repos.d/CentOS-Base.repo

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2.下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)

CentOS7:wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
CentOS6:wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
CentOS5:wget http://mirrors.163.com/.help/CentOS5-Base-163.repo

3.运行以下命令生成缓存

yum clean all
yum makecache
